Transformation of Networks through Cognitive Approaches [article]

T.R.Gopalakrishnan Nair, Abhijith, Kavitha Sooda
2010 arXiv   pre-print
The growth in data traffic and the increased demand for quality of service had generated a large demand for network systems to be more efficient.  ...  The cognitive elements of a system like perception, learning, planning, reasoning and decision forming can enable the systems to be more aware of their environment and offer better services.  ...  Reinforcement Learning problems are typically modeled by means of Markov Decision Processes (MDPs) [18] .  ...

High-Level Design Approach for the Specification of Cognitive Radio Equipments Management APIs

Christophe Moy
2009 Journal of Network and Systems Management  
The HDCRAM adds to the HDReM's reconfiguration management facilities the necessary new management features, which enable the support of sensing and decision making facilities.  ...  We assert that it is necessary to add inside the radio equipments some management facilities for that purpose, and we propose in this paper a high-level design approach for the specification of a management  ...  Indeed, such an object oriented programming approach defines, for the super class, the encapsulation of the object, and allows a free behavioral mechanism for the child classes.  ...
